In electrokinetic separations, the narrower and more homogeneous the initial sample plug, the higher the ultimate resolution of the separation. Here we describe a general and versatile method to sculpt low-dispersion, high-fidelity sample zones in microfluidic devices for high resolution electrokinetic separations. In a simple channel intersections microfabricated partitions act to reduce each ...

Simulation of electrokinetic instabilities using COMSOL Multiphysics

Carl Meinhart
University of California Santa Barbara
Santa Barbara, USA

This presentation shows a number of models of electrokinetic behaviour, each differentiated by a specific assumption. The purpose is to show how such assumptions can lead to varying results in elektrokinetic simulations. --------------------------------- Keynote speaker's biography: Professor Meinhart completed his Ph.D and Postdoctoral work at the University of Illinois in June of 1995. At ...

Einsatz von FEMLAB bei der Optimierung der Geometrie eines Hochspannungsimpulstransformators

Cernat, R.1, Brinkmann, C.1, Weißgerber, T.2
1 Universität Dortmund, Lehrstuhl für Hochspannungstechnik und EMV
2 era GmbH, Dortmund

Hochspannungsimpulstransformatoren werden bei Ottomotoren zur Entzündung des Kraftstoff- Luft-Gemischs eingesetzt. Aktuelle Fahrzeuge sind mit zylinderselektiver Zündung ausgerüstet, so dass für jeden Zylinder ein Zündtransformator benötigt wird. Dieser ist direkt über der Zündkerze positioniert und stellt die benötigte Hochspannung sowie eine ausreichende Funkenenergie zur Verfügung, ...

A Domain Decomposition Algorithm for Dissipative or non Dissipative Acoustic Cavities

Balabane M.
University Paris 13 - Math. dpt.

This note is devoted to a domain decomposition method solving the Helmholtz equation in the frequency domain. We need to perform this global computation as a sequence of local computations, each computation being performed on a single subdomain, without any knowledge of the geometry and meshing of the other subdomains. This is useful when the global geometry is too big to be stored in a single ...

A Model of SuperRens Effect to Describe Future Generation Optical Data Storage

Gidon, S., Hyot, B., Poupinet, L.
CEA Grenoble Leti

In the quest for a higher data storage capacity, different solutions for the future generations of optical discs (after the Blu-ray format, BD) are under investigations. An increase of the NA beyond 0.85 (NA of the BD format) requires the use of near field optics with all the difficulties inherent to those techniques (fine control of the distance between the optical head and the media). Today ...

FEMLAB modules for bioengineering education

Butler, P.J.1, Ferko, M.C.2
1 Department of Bioengineering, Penn State University
2 Stryker Orthopedics Corporation

As biologists uncover the structural and functional complexity of living organisms, it is increasingly clear that mathematical models are needed to synthesize experimental data and predict biological responses to external stimuli. Bioengineers are well-suited to develop such models and to add mechanics, fluid flow and other physical cues to the understanding of biological structure and ...
